Computational Orthographic Image Generator

Non-Confidential description of the invention

Invention can count objects which are stacked on top of each other or a bundle of objects by taking a series of snapshots by a digital camera or an array of cameras with their optical centers belonging to a plane and then computationally stitch them to provide an orthographic view of the scene for counting objects or even do dimensional measurement. The intervals between captures can be adjusted depending on the amount of occlusions and unevenness of the surface. Count/Measurements can be performed by using image processing techniques. In current art, a telecentric lens is used to optically generate an orthographic view. Our invention removes the need for costly and heavy apparatus like the telecentric lens and eliminates many of the disadvantages of the current art. One such disadvantage is the limited aperture of the lens which remains fixed for a given lens, whose price increases nonlinearly with aperture size. Our alternative allows an aperture with variable shape and size tailored to requirement, also at much lower cost.
